' SPRING ATTACHMENT FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 394,624, dated December 18, 1888. Application filed eptember 2Q, 1887. Serial No. 250,941. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN V. B. \VAL- DORF, of \Volcott, in the county of \Vayne and State of New York, have invented certain Improvements in \Vagon-Body- Gpring Attachments, of which the followin is a specification.

The object of my invention is the provision of a spring attachment that can be sold in the market and easily adjusted by the purchaser to any wagon having bolsters, stakes, or their equivalents to sustain a wagon-body or to be used as a seat in the absence of the wagon-body; and to this end the improvement consists, essentially, in a plate provided with grips for securing a conical or cone-sustaining spring, and with adjustable guides to engage the bolster and with slots and spurs to engage the stakes or equivalent part of the vehicle, which hereinafter will be more fully described or claimed, and shown in the annexed drawings, in which Figure 1 is a perspective view of a bolster embodying my invention; Fig. '2, a perspective view of the plate having slots and bolts passing through the slots for securing the plate to the springs on which it rests; Fig. 3, a perspective view of the base-plate, showing grips and spurs and sub-plate in one piece; Fig. Al, a perspective view of the adjustable guide, with slot and bolt hole; Fig. 5, a crosssection on the line X X of Fig. l, on an enlarged scale, showing adjustable guides, bolts through bolster, rubber cone, spring, stake, and base-plate.

The bolster A, having the stakes a at each end, is of common construction and is provided with the base-plates B near each end, which are located just inside the stakes and have lugs 19, that embrace the sides of the stakes a to strengthen the said stakes and prevent lateral movement of the plates B. The plates B rest on the brackets C, that are secured to the sides of the bolster by the bolt D, and are secured to the brackets C by the bolts E, which pass through the slots 6 in said brackets. By having the brackets slotted they can be applied to bolsters of varying thickness and yet have the plates B secured thereto.

The coil-springs F are secured to the plates B by the lips I), which fit over the lower convolutes of the springs, and by the pin 19 and the bolt b which embrace the ends of the said springs. d, fitted within the springs, re-enforce them and prevent the pounding of the vehiclebody or the plate G on the base-plates B. The chains ll, interposed between the bolster and the plate G, connect the two and prevent the plate separating from the bolster too far on the recoil of the springs.

The plate G is composed of two plates, 9 and g, which have a series of coincident slots, g through which the bolts g pass, that secure the plates together and to the springs. At oneend a short plate or slide, 9 is provided, so that the plate G may be lengthened and shortened equally at each end to fit snugly between the stakes 0.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination, with the bolster and the brackets having slots 6, of the base-plates B, secured to the bolster by bolts passing through the slots in the brackets, and the springs secured to the base-plates, substantially as described.

2. The combination, with the bolster and the base-plate having the spurs or lips I), of the spring fitted under the said lips, and the pin b and bolt 1/ for securing the end of the spring, substantially as described.

3. The combination, with the bolster having the stakes and the base-plate secured to the bolster and having lugs 11, which embrace the sides of the stake, of the spring secured to the base-plate, substantially as described.

4. The combination, with the bolster and the springs, of the plate G, secured to the springs and composed of two parts which are adjustably connected together, substantially as described.

5. The combination of the bolster having stakes at each end, the brackets C, secured to the sides of the bolster and having slots 9, the base-plates secured to the brackets and having lugs b, which embrace the sides of the stakes, and having the lips I), the springs, the cushions (l, the adjustable plate G, and the chains H, substantially as and for the purpose described.
